Answer:

-2

Step-by-step explanation:

- 5x + 8 = 18

Take + 8 to the right hand side, it turns negative i.e -8

-5x         = 18 - 8

-5x         = 10

Divide both sides by the coefficient of x which is -5  

-5x/5          = 10/-5

x = -2

Ms. Hagan invested twice as much money in an account that pays 7% interest as she did in an account that pays 6% in interest. He
Karo-lina-s [1.5K]

Answer: She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.

Step-by-step explanation:

Let P be the initial amount she invested in an account that pays 6% interest.

Then, amount invested in other account = 2P

Simple interest = Principal x rate x time

After one year, for the first account,

Interest = P(0.06)(1)  = 0.06P

For second account,

Interest = (2P)(0.07)(1)=0.14P

Total interest = 0.06P+0.14P=1000

\Rightarrow\ 0.20P=1000\\\\\Rightarrow\ P=\dfrac{1000}{0.20}\\\\\Rightarrow\ P=5000

2P = 2(5000)=10000

Hence, She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.

In a reflection, pairs of corresponding points lie on parallel lines.<br> True or False?
Lerok [7]

The statement that: pairs of corresponding points lie on parallel lines in a reflection, is false.

<h3>What are reflections?</h3>

When a point is reflected, then the point is flipped across a point or line of reflection

When a point is reflected, the following highlights are possible

  • The corresponding points can line on the same line
  • The corresponding points can line on parallel lines

Using the above highlights, we can conclude that the statement is false.

This is so because, corresponding points are not always on parallel lines
